Note 428 — Chapter XII
Reading edition
The poetess has, however, not been literally accurate regarding the Nautilus and its habits, nor as to the formation of stratified rocks, but has given a romantic rather than a scientifically correct view of this interesting Cephalopod, and of the disappearance of its congener. The young reader must, therefore, remember that the Nautilus sometimes floats, but never sails; and that the whole race of Ammonites died out in course of time, and were not annihilated by convulsive movements of earth and sea.
